Configuring from /home/opam/.opamrc-sandbox, then /home/opam/.opamrc, and finally from built-in defaults.
Checking for available remotes: rsync and local, git.
- you won't be able to use mercurial repositories unless you install the hg command on your system.
- you won't be able to use darcs repositories unless you install the darcs command on your system.
This version of opam requires an update to the layout of /home/opam/.opam from version 2.1 to version 2.2, which can't be reverted.
You may want to back it up before going further.
[NOTE] The 'jobs' option was reset, its value was 1 and its new value will vary according to the current number of cores on your machine. You can restore the fixed value using:
opam option jobs=1 --global
